JA88 Rear Differential
The JA88 rear differential is intended for powersports and utility vehicle drivetrains where packaging flexibility, controlled torque transfer and consistent service performance are important. Its application can be reviewed for rear-axle layouts used on UTV, SSV and specialized off-road equipment. OEM engineers should evaluate reduction ratio, mounting points, shaft interfaces, lubrication, thermal loading and expected shock loads as part of vehicle integration. Zhejiang Jessica Transmission provides engineering communication, dimensional review, sample coordination and manufacturing support from validation through serial supply. Final suitability depends on the complete vehicle duty cycle, including payload, tire diameter, terrain, operating speed and environmental exposure. Contact the Jessica team for drawings, application guidance and quotation details.
